This guide serves as a practical manual for foresters looking to implement the shelterwood cutting method in British Columbia. As the third part of a three-part series, this guide builds upon previous parts by focusing on the specific harvesting operations involved in this silvicultural system. The guide emphasizes that each harvest entry is a deliberate silvicultural treatment designed to manipulate the forest environment to achieve regeneration and stand-tending objectives, highlighting key considerations like protecting the soil, existing trees, and new growth while promoting a favorable environment for the next forest generation.

This paper examines the costs and productivity of different timber harvesting methods in the interior wet-belt of British Columbia, specifically focusing on maintaining habitat for mountain caribou. The study compares group selection harvesting, where small patches of forest are removed, with clearcutting and single-tree selection. Its primary purpose is to document the economic implications of a harvesting approach designed to balance timber extraction with the ecological needs of caribou in old-growth cedar-hemlock forests.

This extension note presents a case study on using partial cutting to reduce the susceptibility of mature Lodgepole Pine stands to Mountain Pine Beetle attacks, a process termed Beetle Proofing. The document details the objectives and criteria for this forestry practice, emphasizing proper layout, experienced logging contractors, and a commitment to overall parties. It outlines the harvesting and silviculture systems involved, explaining how selective removal of trees aims to create a stand structure that is less vulnerable to beetle infestations, rather than a clear-cut approach. This document serves as a guide for forest management, outlining management objectives and planning for sustainable timber production and biodiversity while mitigating the impact of MPB in the British Columbia interior.

This document details a study conducted in British Columbia's Interior Cedar-Hemlock forest where the primary focus is evaluating the productivity and costs of ground-based harvesting methods under different silvicultural prescriptions: clearcut, heavy removal, and light removal. The study monitored various harvesting systems, including mechanized, conventional, and horse skidding, to understand their economic implications and impact on the site. The research aimed to inform the development of sustainable forestry practices that balance timber production with ecological considerations in the region.

This case study details a study comparing different methods of harvesting trees in a coastal montane forest in British Columbia. Prompted by concerns about regeneration success at higher elevations and public desire for alternatives to clearcutting, the Montane Alternative Silvicultural Systems project investigated the productivity and costs associated with uniform shelterwood, green tree retention, and patch cutting compared to traditional clearcutting. The study tracked the efficiency and expense of falling and forwarding operations, alongside measuring the impact on soil disturbance and the amount of remaining woody debris. Ultimately, the research aimed to provide insights into the economic and operational feasibility of alternative silvicultural systems in this challenging environment, while also considering their long-term ecological effects.

This document serves as a reference handbook about the key factors influencing the successful application of various timber harvesting equipment and systems in the region. The handbook systematically explores primary transport equipment, categorized into ground-based, cable, and aerial systems, detailing their operational characteristics, environmental considerations, and distinguishing features. By outlining the advantages and limitations of each technology, the guide empowers readers to make informed judgments about equipment selection based on specific site conditions and harvesting objectives, emphasizing that no single best system exists for all situations.

This document is a comprehensive reference for harvesting systems and equipment used in British Columbia. Part one addresses equipment selection by outlining key factors, summarizing equipment characteristics by harvesting phase, and providing a risk-level assessment for various equipment and site combinations. This handbook aims to improve the understanding of loggers and planners in British Columbia, enabling them to make better-informed decisions when choosing the most suitable harvesting systems and equipment for diverse site conditions and management objectives, without prescribing a single correct solution.
